I'd suspect Ghost Of Tsushima is the PS5 launch window title.
Here's the thing, if the launch occurs during the holiday quarter rush, then its up against all the big third-party competition. That's sucking a lot of air out of the market already, and its additionally a good time to allow them to make as much bank as possible so they'll continue to give support to your ecosystem.
TLOU2 is simply too big of a deal to be fed into that. Death Stranding makes sense as its counter-programming against the mainstream offerings.
